We look at the division of 43384429 by 126 
Our goal is to divide 43384429 by 126.

Let's proceed to step 1:
126 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 126

Moving on to step 2:
43 divided by 126 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Grab the next digit (3) from the dividend, add it to 43, then carry on: 433 / 126

On to step 3:
When dividing 433 by 126, we get 3 with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 378 from 433 and we're left with 55.
Grab the next digit (8) from the dividend, add it to 55, then carry on: 558 / 126

Advancing to step 4:
If we divide 558 by 126, we get 4 and a remainder of 54.
The next digit of our result is 4. 
Result so far: 34.0
The remainder is 54 after subtracting 504 from 558.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 126

Step 5:
126 can be fit into 544 4 times, resulting in a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 344.0
The remainder is 40 after subtracting 504 from 544.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 126

Going ahead to step 6:
126 can be fit into 404 3 times, resulting in a remainder of 26.
The next digit of our result is 3. 
Result so far: 3443.0
The remainder is 26 after subtracting 378 from 404.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 126

Let's proceed to step 7:
126 can be fit into 262 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 34432.0
Subtract 252 from 262 to get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 126

Going ahead to step 8:
109 divided by 126 is 0 with a remainder of 109.
The number 0 becomes the next digit in our result. 
Result so far: 344320.0
Subtracting 0 from 109 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Moving on to step 9:
126 goes into 1090 8 times with a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 344320.8
Subtract 1008 from 1090 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 10:
If we divide 820 by 126, we get 6 and a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 344320.86
Deduct 756 from 820 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
If we divide 640 by 126, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 344320.865
Deduct 630 from 640 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
If we divide 100 by 126, we get 0 and a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 344320.865
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 13:
1000 divided by 126 is 7 with a remainder of 118.
Record the quotient 7 as the next digit in the result. 
Result so far: 344320.86507
If we take 882 away from 1000, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 14:
126 can be fit into 1180 9 times, resulting in a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 344320.865079
If we subtract 1134 from 1180, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 15:
460 divided by 126 is 3 with a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 344320.8650793
Deduct 378 from 460 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 16:
If we divide 820 by 126, we get 6 and a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 344320.86507936
If we subtract 756 from 820, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 344320.86507936 and a remainder of 6.4e-08.
